Apparatus and method for stabilizing terminal power in a communication system

Abstract

An apparatus and method are provided for stabilizing terminal power in antenna ports. A data transmission / reception method is provided for terminal power stabilization in a communication system using multiple antennas. An optimal antenna immune to absorption loss due to human body proximity is selected from among multiple antennas connected to a single port when a data service is provided. Data for the data service is transmitted and received through the selected antenna.

Problems solved by technology

Conventionally, the performance and capacity of a communication system are limited due to radio wave channel characteristics such as interference signals of the same channel occurring between cells or within a cell, path loss, multipath fading, signal delay, Doppler spreading, shadowing, and so on.

However, existing technologies have great difficulty in providing high performance, large capacity services.

Conventionally, the absorption loss is power loss of a signal passing through an adjacent circuit or conductor in a communication circuit.

When a user uses its terminal executing various applications such as game, video and call services, a problem may arise in that the electronic wave reception may be weak due to the user's hands or other adjacent devices near or around the antenna of the terminal.

For example, when the user plays a game on the terminal, the user's hands may interfere with a received electronic wave depending on the antenna position.
